Description
One, technical field:
The utility model relates to testing machine, more specifically is meant a kind of universal testing machine four column adjustable mechanisms that are applicable to the performance test and the research of metal, nonmetallic materials.
Two, background technology:
Present universal testing machine both domestic and external mostly adopts two column frame structures, and the main frame height is at 3100-3900mm, stretching space 900-780mm, main frame height and stretching space are lower, oil cylinder be top loaded type automatic aligning device, the no automatic aligning device of oil cylinder low-laying type arranged, sample is subject to side force and disturbs, the main frame right alignment is relatively poor, and hydraulic chuck is generally manually, operation inconvenience, jaw seat resistance to abrasion is poor, crimping easily takes place, also do not have dust guard, anchor clamps and bearing cleaning trouble.The external adopts pressure sensor mostly of data processing detects the power value, detects distortion with strain gauge; Detect piston displacement with displacement transducer, carry out data acquisition and processing (DAP) by single-chip microcomputer or microcomputer.
Three, summary of the invention:
Key problem in technology to be solved in the utility model is: reduce the main frame height, improve the ratio in main frame height and stretching space, strengthen beam strength, reduce distortion, improve stressed uniformity coefficient of jaw and right alignment, increase the resistance to abrasion of jaw seat, stopping crimping takes place, improve complete machine serviceable life, make complete machine flexible to operation, the utility model is to consider so for this reason: main frame is the oil cylinder low-laying type, double space, four column frame structures connect with four root posts between entablature and the examination platform, form two work spaces with the sill of centre, tension test can be carried out in last space; Tests such as following space can be compressed, bending, shearing, column below are provided with a plurality of ring grooves, and when snap ring will try decometer in the above in two grooves the time, test space is a minimum.Remove snap ring, column string on examination platform centre is moving, when being stuck in snap ring in following two ring grooves, and the test space maximum.Because column can string be moving up and down in the examination platform, it is a lot of that the main frame height is reduced, and the adjustment position of column is in the bottom, and is hidden in coaming plate, so profile is carefully and neatly done, easy to adjust, because four columns supporting entablature, when carrying out tension test, jaw is stressed evenly, right alignment is good, and no unbalance loading phenomenon has also improved beam strength simultaneously.
Oil cylinder, piston are contained on the base, and load (power) sensor, examination platform, entablature, sill are housed above it.In the upper and lower crossbeam hydraulic chuck is housed, supporting plate is at the jaw center, and clamping force is in jaw central authorities, and clamping is reliable.
At main frame oil cylinder internal piston, a spheric seating is housed, on the seat aligning bulb pole, because it is gapped between a thick stick and piston and the adjustment volution, during test, entablature, column, examination platform, load sensor, aligning bulb pillar are a rigid body, on the folder behind the sample, aligning bulb pole is along with stressing conditions is swung on spheric seating, thereby reach the automatic aligning effect, because pole at the piston center, does not have side force between piston and cylinder wall, eliminated between the two and rubbed, also improved machine life.
Loosening, tighten by manual control box of the adjustment in space and hydraulic chuck handled up and down, and manual control box can move arbitrarily, and magnet is equipped with in the back, and the operation that can be placed in testing machine is eaily on the position, and interlock function in addition between the two, prevents maloperation.
General large-tonnage testing machine is long working time one, and wearing and tearing will appear in jaw, even therefore complete machine scrap, and installs wearing plate, facing plate on jaw additional for this reason, improves complete machine serviceable life.
At the stretched blank sample or when the sample of oxide skin is arranged, often there are foreign material or oxide skin to come off, fall into the joint portion of jaw clamp, make the wearing and tearing of jaw or clamp, for this reason, the utility model is equipped with flexible dust guard.
Omnipotent machine because web member is gapped, can make trial curve flex point occur when testing, and influences test figure, for this reason, is added with two nut supports and spring on sill, holds up for propping up the sill of naming a person for a particular job with leading screw, eliminates the gap of nut.
For making product play the security warning effect, main frame and oil supply system, support and fuel tank adopt and divide the colored paint decorations.
Four, description of drawings:
Accompanying drawing 1 is the utility model main machine structure positive view;
Accompanying drawing 2 is the utility model main machine structure side view;
Accompanying drawing 3 is four column frame structure height adjustment and automatic aligning device synoptic diagram;
Accompanying drawing 4 is a hydraulic chuck, gap eliminator, wearing plate, facing plate, dustproof sheet structural representation.
Accompanying drawing 5 is the electrical equipment control schematic diagram.
Five, specific implementation method:
With reference to the accompanying drawings 1, the utility model is by base 1, oil cylinder piston group 2, aligning device 3, load sensor 4, examination platform 5, sill 6, hydraulic chuck 7, column 8, compositions such as leading screw 9, entablature 10, orienting sleeve 12.
Connect with four root posts 8 between entablature 10 and the examination platform 5, with reference to the accompanying drawings 3, there are 4 ring groove 8-1 column 8 belows, when snap ring 8-2 will try platform 5 be stuck in above in two grooves the time, the test space minimum, remove snap ring 8-2, column 8 string in examination platform 5 is moving, when being stuck in snap ring in following two grooves, and the test space maximum, snap ring is equipped with snap ring cover 8-3 on examination platform 5, snap ring connecting plate 8-4 is housed below, and column is adjusted the position in the bottom, and is hidden in coaming plate 8-5, four columns supporting entablature 10, fixing with nut 11.
4 last with reference to the accompanying drawings, the middle part of sill, hydraulic chuck 7 is housed, hydraulic chuck 7 is by chuck oil cylinder 7-1, chuck piston 7-2, oil cylinder blocks up 7-3, jaw supporting plate 7-4, jaw clamp 7-5, compositions such as jaw 7-6, jaw supporting plate 7-4 lower end is contained on the chuck piston 7-2, the upper end is embedded in the bayonet socket of jaw clamp, and jaw is installed on the jaw clamp, because last, the hydraulic chuck position of sill is beveled, therefore when the chuck piston rises, jaw just clamps, otherwise then unclamps, in order to prolong main frame serviceable life, on the position, inclined-plane of the lower and upper cross-member corresponding wearing plate, facing plate 7-7 is housed with the jaw clamp, fall into jaw for preventing that foreign material and oxide skin from coming off simultaneously, dustproof sheet 7-8 is installed between crossbeam mouth and jaw clamp, dustproof sheet is the sheet rubber that is the Ω type.
Because web member is gapped, can make trial curve flex point occur, the curve of influence test adds two nut support 6-1 and backlash spring 6-2 for this reason on sill, be fulcrum with leading screw 9, and sill 6 is held up the gap of having eliminated nut.
The lifting of sill and the degree of tightness of hydraulic chuck are handled by manual control box, manual control box can move arbitrarily, and magnet is equipped with in the back, can be placed in main frame place arbitrarily, with reference to the accompanying drawings the lifting of 5 sills and up and down the degree of tightness switch of hydraulic chuck have interlock function, prevented maloperation.
